Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs). Dmitri Mendeleev atomicchemicalelement Change image and share on social

The establishment of a law, moreover, does not take place when the first thought of it takes form, or even when its significance is recognised, but only when it has been confirmed by the results of the experiment. Dmitri Mendeleev confirmestablishmentexperiment share on social
We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75. Dmitri Mendeleev aluminumanalogousatomic Change image and share on social
The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body. Dmitri Mendeleev atomicbodycharacter Change image and share on social
